4 cards from this section. Quick, good the night before a test.
What is the molarity of a solution containing 1 mole of NaCl in 2 liters of water?
Use the formula M = moles of solute / liters of solution.
How do you calculate molality?
Remember to use kilograms for the mass of the solvent.
What unit is used to measure molarity?
Think about how molarity is defined.
True or False: Molality is affected by temperature changes.
Recall how molality is defined.
You have a solution that is 0.250 M NaCl. How many grams of NaCl are in 500 mL of this solution?
Start by calculating moles using molarity.
A solution is prepared by dissolving 5 grams of KCl in enough water to reach a final volume of 250 mL. What is the molality if the solvent mass is 200 g?
Remember to convert grams of solvent to kilograms.
